Product Features
1. Be careful to prevent the filter membrane clip from accidentally falling off or being damaged during use to avoid injury.
2. Avoid exposing the filter membrane clip to fire or high-temperature objects to prevent fire hazards or the release of harmful substances.
3. When collecting liquid samples, it is recommended to use a filter membrane with a larger pore size to prevent deformation of the clip and leakage.
Frequently Asked Questions (FAQ)
What are the primary applications of the PTFE Filter Holder?
The PTFE Filter Holder is mainly designed for filtering gases, strong acids, and alkaline solvents. It is also widely used for aerosol sampling, low-concentration particle sampling, and environmental monitoring.
What sizes of PTFE Filter Holders do you offer?
We offer a wide range of standard sizes to meet different experimental needs, including 13mm, 25mm, 37mm, 40mm, 47mm, 50mm, and 90mm.
Why is PTFE chosen as the material for these holders?
PTFE offers outstanding chemical stability, making it highly resistant to acids, alkalis, and weather. It has a low friction coefficient, high lubricity, and low surface adhesion, which significantly minimizes sample residue buildup.
How can I prevent leakage when collecting liquid samples?
To prevent deformation of the filter membrane clip and subsequent leakage, it is highly recommended to use a filter membrane with a larger pore size during liquid sample collection.
Are there any temperature restrictions when using the filter holder?
Yes, you should avoid exposing the filter membrane clip to direct fire or high-temperature objects. Extreme heat can damage the clip and release harmful substances.
Does the PTFE material absorb moisture?
No, PTFE has excellent weather resistance and does not absorb moisture. It remains highly stable when exposed to oxygen and ultraviolet light.
